Adnaut. After-hours mission control lit by sodium lamps.

Primary CTA fills, active nav indicators, accent card backgrounds, logo wordmark, and the single chromatic punctuation across an otherwise monochrome system

Editorial accent — one or two keyword words per page glow in this green to carry emphasis and keep the palette from feeling monochrome

Page background canvas — the near-black with a barely-warm tint that anchors the entire system

Elevated card surfaces, outlined button borders, and the primary border tone for sections that need separation from the canvas

Deep accents within dark illustrations and subtle depth layers where pure black would feel too harsh

Secondary borders, divider lines, and inactive control outlines where a softer edge is needed

Muted helper text, metadata, and secondary link colors where legibility matters less than hierarchy

Primary body and UI text — the off-white that softens contrast against the carbon canvas and reduces eye strain across long reading passages

Headline and display text on dark surfaces — a step brighter than Frost, reserved for the largest type that needs extra punch

Text on yellow fills and inside bright accent cards; the only acceptable text color over Sodium Yellow
